Video tutorials of body opener can be found in many places, such as Aauto Quicker, Tik Tok and other software for brushing videos. Of course, there are also many related resources for your reference on BiLi and Baidu.

1.

There are many video tutorial resources, just enter keywords, but it is inconvenient to register and log in to watch videos. In this case, I suggest using Baidu to find video tutorials.

2. Baidu (the world's largest Chinese search engine)

Baidu doesn't need to register to watch videos. Only you can open the browser of Baidu. However, the online evaluation of the back opener is different. Some people think it is useful, others think it is paying an "IQ tax". In short, choose the one that suits you, don't blindly follow the trend, and finally hurt your health.
